The Sucker (movie, 1965)

In this Frenco-Italian gangster parody, a shop keeper on his way to an Italian holiday suffers a crash which totals his car. The culprit can only compensate his ruined trip by driving an American friends car from Napels to Bordeaux, but as it happens to be filled with such contraband as stolen money, jewelry and drugs, the involuntary and unwitting companions in crime soon attract all but recreational attention from the "milieu".
